摘要：A natural gas hydrate drilling simulation device, includes a hydrate rock coresimulation system, a drilling system, a drilling fluid injection system and a drilling fluid

treatment system. The hydrate rock core simulation system includes a hydrate formationsimulation wellbore, an artificial rock core, a water bath jacket and low temperaturewater bath. The drilling system includes a bracket, a high pressure rotary connectingdevice, a hydraulic device and a drilling device. The drilling fluid injection system includesa mud tank, a drilling fluid flowmeter, mud pumps and an overflow valve. The drilling fluidtreatment system includes a high pressure sand remover, a back pressure and overflowcontrol system, a gas-liquid separator, a dyer, a gas flowmeter, a liquid flowmeter and amud treatment tank. This natural gas hydrate drilling simulation device performssimulation experiments under a variety of downhole working condition environments.
